Benefits of technology
The patent describes a climate control system that allows multiple fan motors to be connected to a control unit using interchangeable wiring. This allows for easy swapping of fans and ensures that the system operates correctly. The control unit automatically detects the wiring configuration and operates the fans accordingly to heat or cool the interior space. The technical effect of this invention is improved flexibility and efficiency in climate control for buildings and other interior spaces.
Problems solved by technology
This process causes the refrigerant to become hot.
However, having more than one fan results in additional complexity and cost in the manufacturing and servicing of the indoor unit.

Embodiment Construction
[0012]FIG. 1 is a perspective diagram of climate control system 10. Climate control system 10 includes indoor unit 12, outdoor unit 14, and pipes 15. Climate control system 10 is a heat pump, chiller, air conditioner, or similar device that is capable of transferring heat between interior air and outdoor air to heat and / or cool an interior space. Indoor unit 12 includes a control unit, a coil, and fans, as described in more detail with reference to FIG. 2. Outdoor unit 14 includes a compressor, a coil, and a fan. A refrigerant is passed through the coils of the indoor unit and the outdoor unit, and is compressed by the compressor. Refrigerant flows within the coils of indoor unit 12 and outdoor unit 14, and through pipes 15 that connect between indoor unit 12 and outdoor unit 14.
[0013]FIG. 2 is a perspective diagram of indoor unit 12 broken apart to illustrate the internal components. Indoor unit 12 includes front panel 16, case 18, control box 20, coils 22, vertical flaps 24, fans ...

A climate control system (10) includes an outdoor unit (14) and an indoor unit (12) having at least two fans (26,28). The fans (26,28) include control wiring (38,40) that is interchangeably connected to a control system (20), and feedback wiring (42,44) that is also interchangeably connected to the control system (20). The control system (20) is capable of automatically detecting the wiring configuration of the control wiring (38,40) and the feedback wiring (42,44). The climate control system (10) operates the fans (26,28) according to the detected wiring configuration to heat or cool an interior space.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to a climate control system, and more particularly to a climate control system with automatic wiring detection.[0002]Climate control systems such as heat pumps are used to heat interior spaces by transferring heat between the outside air and the inside air. As a result, climate control systems generally include an indoor unit and an outdoor unit. A refrigerant flows between the indoor unit and the outdoor unit. Within the indoor and outdoor units, the refrigerant passes through coils where it heats or cools the surrounding air.[0003]Heating and cooling of the indoor space is accomplished by adjusting the pressure of the refrigerant within the coils to cause the refrigerant to undergo the phase changes of an evaporation cycle. To cool an indoor space, the climate control system utilizes a compressor to compress the refrigerant from a low-pressure gas to a high-pressure gas. This process causes the refrigerant to become ho...
